DRAINAGE

1. The surface tensile strength and hardness of the pipe are excellent, and the safety factor of the pipe is relatively high.
2. The anti-aging performance is good, and the service life of normal PVC drainage pipes can reach more than 50 years.
3. The pipeline has excellent corrosion resistance to inorganic acid, alkali and salt, so it is suitable for the transportation and discharge of industrial sewage.
4. The internal friction coefficient of the pipeline is small, the water flow is smooth, the blockage is not easy to occur, and the maintenance workload is small.
5. The oxygen index in the material is high, and the pipeline is self extinguishing.
6. The expansion coefficient of the pipeline is small, normally 0.07mm/??, and the deformation is small due to tempAPASture. At the same time, its thermal conductivity and elastic modulus are also small, and its frost resistance is better than that of cast iron drain pipes.
7. The connection between pipes and pipe fittings can be made by bonding, which is simple in construction, convenient in opAPAStion and efficient in installation.
8. Whether the PVC-U pipe is installed by bonding or rubber ring connection, the pipe has good water tightness.

PVC-U pipe is made of sanitary grade polyvinyl chloride (PVC) resin as the main raw material, and added with appropriate amount of stabilizer, lubricant, filler, color enhancer, which is extruded by plastic extruder and molded by injection molding machine. The production of pipes and pipe fittings is completed through cooling, curing, shaping, inspection, packaging and other processes.PVC water pipes have great advantages in physical and chemical properties. It is made of unique mechanical and physical properties. The service life of this kind of pipe can be as long as 50 years. At the same time, it has many characteristics such as corrosion resistance, aging resistance and wear resistance.The deformation affected by tempAPASture is small, 50% – 150% lower than that of similar pipes. Its thermal conductivity and elasticity are small, and its frost resistance is better than some metal pipes.

The surface hardness and tensile strength of pvc drainage pipes are excellent, and the pipeline safety factor is extremely high.The linear expansion coefficient of pvc drainage pipe is small, 0. 07mm/℃, small deformation due to temperature. Small thermal conductivity and elastic modulus, excellent frost resistance.PVC rainwater pipes have excellent toughness, and the surface hardness and tensile strength of pipe fittings are excellent. PVC drainage pipe can be connected by bonding method, which is simple in construction, convenient in opAPAStion and installation.PVC drainage pipe has good aging resistance, and its normal service life can reach more than 50 years.Pvc drainage pipe has excellent corrosion resistance to inorganic acid, alkali, salt and other substances, so it is more suitable for industrial sewage discharge and transmission.

1. Pvc drainage pipe has good tensile and compressive strength, but its flexibility is not as good as other plastic pipes.
2. The wall of PVC drainage pipe is very smooth, so the resistance of water flow is very small. Its water delivery capacity is 20% higher than that of cast iron pipe with the same pipe diameter, and the water delivery effect is very good.
3. In addition, the corrosion resistance and drug resistance of pvc drainage pipe are also very good, with good acid and alkali resistance characteristics. It is not affected by moisture and soil pH, and has a long service life.
4. Pvc drainage pipe also has good water tightness. this pipe can maintain good water tightness whether it is connected by adhesive or rubber ring.

1. Light pipes and convenient construction
The specific gravity of PVC drainage pipe is about 1.4t/m3, which is only 1/5 of that of cast iron pipe. Plastic pipes of the same length are much lighter than cast iron pipes, requiring only manual handling during installation. In addition, PVC drainage pipes use socket type adhesive joints. At the same time, their standard length (6m, 4m) is longer than that of cast iron pipes, reducing the number of joints and installation procedures.
2. Good drainage performance
The diameter of PVC drainage pipe can be smaller than that of cast iron pipe, or the same pipe diameter can use a smaller slope within the allowable scope of the specification as far as possible, so as to increase the clear height of the space, which is more beneficial to users and enhances the use function of the building.
3: Economical and beautiful
PVC drainage pipes are usually white on the outer wall, and do not need to be painted with red lead, silver powder and other anti-corrosion treatments. There is no such problem as the corrosion and peeling of the outer wall of the cast iron pipe. When they are concealed into the pipe well, they do not need frequent maintenance and care. The advantages of open installation are more obvious than the cast iron pipe: easy to clean, less harmful to visual effects, which greatly improves people’s life and working environment, and also facilitates the property management of buildings.
4. Good social benefits
PVC drainage pipe can replace other steel drainage pipes in a large range, and greatly reduce the energy consumption in the steelmaking process.
5. Superior physical and chemical properties
PVC drainage pipes have stable chemical properties and unique mechanical and physical properties that enable them to be used normally for 50 years. At the same time, their corrosion resistance, aging resistance and wear resistance also enable them to be used more stably for a long time than cast iron drainage pipes and cement pipes
